Can I ask what the mess are for? By the sounds of it, it's for mental reasons. If that's the case then that could be a huge reason this has come about.
I do understand your hurt but in MHO your doing more damage than good, both to your H and your D's. I haven't read your whole story yet and I know at some point you have to let your D's figure this out for themselves but I think you could have maybe texted H and told him how D was feeling. She may have even came to you, hoping you would text him. I know you shouldn't have to but maybe it would have prevented such a damaging event for your D. I know it's all trial and error and I know your only doing what you feel is right ( that's all we can do.) but I think you might be letting your anger towards him, cloud your judgement for the greater good.
The text messages did sound a little harsh and cold towards him. It did sound like you were "gloating" about your D's knowing they can count on you but not him. It did sound a lot like you were trying to have them pick your side.
I get where your coming from and it should be his responsibility not yours but I think when it comes to children, we need to overlook our own feeling and do what is best for them. Do anything we can to try to minimize any emotional damage they might receive. We shouldn't have to but in the end it's their well being that is most important.
As I said I haven't read your whole story, no body is perfect and we all make mistakes. I know you are doing what you think is best but this is just MHO!
Take care of yourself and your girls!!
